You don't have to choose between your weight loss and your hair. Richvell built this for women exactly like you — and tens of thousands on weight-loss injections are already using it to keep both.
“About four months in, my hair started coming out in fistfuls. I was genuinely scared to wash it because of what I’d find in the drain. FST-5 was the first thing that actually slowed the shedding.”
“My part kept getting wider and my ponytail got so thin I could wrap it twice. I don’t panic anymore when I see my scalp in bright bathroom lighting.”
“I’d been fighting with minoxidil and hated the shedding and the greasy residue. This didn’t give me any shedding or scalp irritation and my part has tightened up.”
“A couple of friends asked if I’d gotten extensions put in. Honestly, my hair looks better now than it did in my thirties.”
About four months into Mounjaro my hair started shedding like crazy. My part looked wider, my ponytail felt tiny, and I honestly hated seeing all the hair in the shower. I did not want to use minoxidil because I was worried about the shedding phase and having to commit to it forever.
After three months using FST-5 my hair finally feels fuller again. My part does not look as empty. My crown looks better. I am not stressing every time I look in the mirror.
The best part is that I never had to touch my dose. I kept losing the weight and I got my hair back at the same time. I would recommend it to any woman on a GLP-1 who wants something simple and non-greasy.
Formulated by a board-certified dermatologist for the women a GLP-1 leaves choosing between their weight loss and their hair.
Non-hormonal. No minoxidil. No prescription.
“My own mother was on a GLP-1 and losing her hair. Quitting was never an option for her health — so I went looking for something that worked with the medication instead of against it.”
Here is what is actually happening under your skin right now.
Ozempic, Wegovy, Mounjaro and Zepbound work by shutting off your appetite. You eat far less than you used to. Your body does not know you chose this. It reads the drop as a famine.
In a famine your body protects your heart, your brain and your muscles first. Hair is the one thing you can live without. So your body stops sending the grow signal to your follicles and spends that protein somewhere else.
They are still there. They are still alive. They are waiting for one signal that is not coming. Shampoos, vitamins and oils never reach them. So the signal never comes back on its own.
Most hair products only work on the surface. They coat the strand. They clean the scalp. They make your hair feel thicker for one day. Not one of them carries a growth signal down to the root.
Your hair is not the problem. The missing signal is the problem.
Peptides are short chains of amino acids. They are the exact molecule your hair needs to grow.
They are small enough to pass through your scalp and reach the follicle root, four millimetres down.
So the signal arrives at the follicle directly. It does not have to come from your food.
Your body can stay in fat-burning mode.
Your hair still gets the message.
That is the whole point. You do not have to choose between your weight loss and your hair.
You will not have to explain it. Your hair will do that for you.
FST-5 was measured on a four-week independent customer panel of women losing hair the same way a GLP-1 takes it — counted in the shower and in the brush, before and after. Here’s what they found.

I didn’t expect this
I started a weight-loss injection last year and the weight loss has been great, but about four months in, my hair started coming out in fistfuls. Nobody warned me. FST-5 was the first thing that actually slowed the shedding — within about 3 weeks it calmed down, and now at month 4 my part is filling back in.
My hair looks so much fuller
I only bought it out of curiosity, but I’m so glad I did. It took a little over 2 months to see a clear difference, but now my hair looks so much fuller and my part has tightened up. No shedding, no scalp irritation.
Peptides changed everything for me
I’d never heard of peptides before. It’s been 4 months and the results are amazing. A couple of friends asked if I’d gotten extensions put in. Honestly, my hair looks better now than it did in my thirties.
It works like a miracle
My part kept getting wider and my ponytail got so thin I could wrap it twice. I’d tried minoxidil and hated the shedding and greasy residue. After 3 months on FST-5, my part is filling in and my crown looks denser.
My drain is finally clear
I lost 41 pounds on Wegovy and I would not give that back for anything. But month five the shedding started and I cried in the shower more than once. I started FST-5 and by week three there was barely any hair in the drain. Now my part is closing up. I got to keep both.
I stopped hiding my temples
At 55 my temples went thin and I was combing my hair forward to cover it. My doctor said the hair loss was from how fast I dropped the weight. Four months on this and the temples have filled in. I wear my hair back again. That is not a small thing at my age.
My ponytail is thick again
My ponytail got so thin I could feel the elastic go around four times. I could see my scalp at the crown in every photo. I have used FST-5 every night since February. My ponytail is thick again and I do not check my crown in the mirror anymore.
The baby hairs came back first
I noticed my hairline receding about three months into Zepbound. What sold me on this was seeing the little baby hairs come in along the front around week five. They kept coming. My part is narrow now and my hair actually has shine to it again.
One serum. Five compounds. 30 seconds, once a night, before bed. No drug interactions. Stay on your full dose.
On a GLP-1, your hair gets pushed out of its growing phase and into shedding — the grow signal that tells each follicle to keep building and hold the hair it has gets turned down. That's the clump in the shower, the thinning ponytail, the widening part. FST-5 flips that signal back on — turning growing back up and shedding back down — without ever interfering with your medication.
Use FST-5 every night for 100 days. Don't see less shedding and a fuller ponytail? You get every dollar back. Less than 1% of our customers ever claim it.
Most women on GLP-1s consider two options when the shedding starts. Quitting the medication. Stockpiling supplements. Here's how FST-5 compares.
